+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link DocumentProcessorServiceClient}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (documentai.googleapis.com) and default port (443) are used.
+ *   <li>Credentials are acquired automatically through Application Default Credentials.
+ *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
+ * </ul>
+ *
+ * <p>The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * <p>For example, to set the total timeout of processDocument to 30 seconds:
+ *
+ * <pre>{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * DocumentProcessorServiceSettings.Builder documentProcessorServiceSettingsBuilder =
+ *     DocumentProcessorServiceSettings.newBuilder();
+ * documentProcessorServiceSettingsBuilder
+ *     .processDocumentSettings()
+ *     .setRetrySettings(
+ *         documentProcessorServiceSettingsBuilder
+ *             .processDocumentSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * DocumentProcessorServiceSettings documentProcessorServiceSettings =
+ *     documentProcessorServiceSettingsBuilder.build();
+ * }</pre>

+/**
+ * Settings class to configure an instance of {@link DocumentUnderstandingServiceClient}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (documentai.googleapis.com) and default port (443) are used.
+ *   <li>Credentials are acquired automatically through Application Default Credentials.
+ *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
+ * </ul>
+ *
+ * <p>The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * <p>For example, to set the total timeout of batchProcessDocuments to 30 seconds:
+ *
+ * <pre>{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link DocumentUnderstandingServiceClient}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (documentai.googleapis.com) and default port (443) are used.
+ *   <li>Credentials are acquired automatically through Application Default Credentials.
+ *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
+ * </ul>
+ *
+ * <p>The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * <p>For example, to set the total timeout of processDocument to 30 seconds:
+ *
+ * <pre>{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * DocumentUnderstandingServiceSettings.Builder documentUnderstandingServiceSettingsBuilder =
+ *     DocumentUnderstandingServiceSettings.newBuilder();
+ * documentUnderstandingServiceSettingsBuilder
+ *     .processDocumentSettings()
+ *     .setRetrySettings(
+ *         documentUnderstandingServiceSettingsBuilder
+ *             .processDocumentSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link DocumentProcessorServiceClient}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (documentai.googleapis.com) and default port (443) are used.
+ *   <li>Credentials are acquired automatically through Application Default Credentials.
+ *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
+ * </ul>
+ *
+ * <p>The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * <p>For example, to set the total timeout of processDocument to 30 seconds:
+ *
+ * <pre>{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * DocumentProcessorServiceSettings.Builder documentProcessorServiceSettingsBuilder =
+ *     DocumentProcessorServiceSettings.newBuilder();
+ * documentProcessorServiceSettingsBuilder
+ *     .processDocumentSettings()
+ *     .setRetrySettings(
+ *         documentProcessorServiceSettingsBuilder
+ *             .processDocumentSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * DocumentProcessorServiceSettings documentProcessorServiceSettings =

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Settings class to configure an instance of {@link DocumentProcessorServiceClient}.
- *
- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- *   <li>The default service address (documentai.googleapis.com) and default port (443) are used.
- *   <li>Credentials are acquired automatically through Application Default Credentials.
- *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
- * </ul>
- *
- * <p>The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * <p>For example, to set the total timeout of processDocument to 30 seconds:
- *
- * <pre>{@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * DocumentProcessorServiceSettings.Builder documentProcessorServiceSettingsBuilder =
- *     DocumentProcessorServiceSettings.newBuilder();
- * documentProcessorServiceSettingsBuilder
- *     .processDocumentSettings()
- *     .setRetrySettings(
- *         documentProcessorServiceSettingsBuilder
- *             .processDocumentSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * DocumentProcessorServiceSettings documentProcessorServiceSettings =
- *     documentProcessorServiceSettingsBuilder.build();
- * }</pre>

-/**
- * Settings class to configure an instance of {@link DocumentUnderstandingServiceClient}.
- *
- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- *   <li>The default service address (documentai.googleapis.com) and default port (443) are used.
- *   <li>Credentials are acquired automatically through Application Default Credentials.
- *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
- * </ul>
- *
- * <p>The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * <p>For example, to set the total timeout of batchProcessDocuments to 30 seconds:
- *
- * <pre>{@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * DocumentUnderstandingServiceSettings.Builder documentUnderstandingServiceSettingsBuilder =
- *     DocumentUnderstandingServiceSettings.newBuilder();

-/**
- * Settings class to configure an instance of {@link DocumentUnderstandingServiceClient}.
- *
- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- *   <li>The default service address (documentai.googleapis.com) and default port (443) are used.
- *   <li>Credentials are acquired automatically through Application Default Credentials.
- *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
- * </ul>
- *
- * <p>The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * <p>For example, to set the total timeout of processDocument to 30 seconds:
- *
- * <pre>{@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * DocumentUnderstandingServiceSettings.Builder documentUnderstandingServiceSettingsBuilder =
- *     DocumentUnderstandingServiceSettings.newBuilder();

- *     .setRetrySettings(
- *         documentUnderstandingServiceSettingsBuilder

- *             .toBuilder()

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Settings class to configure an instance of {@link DocumentProcessorServiceClient}.
- *
- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- *   <li>The default service address (documentai.googleapis.com) and default port (443) are used.
- *   <li>Credentials are acquired automatically through Application Default Credentials.
- *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
- * </ul>
- *
- * <p>The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * <p>For example, to set the total timeout of processDocument to 30 seconds:
- *
- * <pre>{@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * DocumentProcessorServiceSettings.Builder documentProcessorServiceSettingsBuilder =
- *     DocumentProcessorServiceSettings.newBuilder();
- * documentProcessorServiceSettingsBuilder
- *     .processDocumentSettings()
- *     .setRetrySettings(
- *         documentProcessorServiceSettingsBuilder
- *             .processDocumentSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * DocumentProcessorServiceSettings documentProcessorServiceSettings =
- *     documentProcessorServiceSettingsBuilder.build();
- * }</pre>
